The Ziro Platform

The fastest way to Teams Phone — and the easiest way to run it.

Assess what you have, migrate in days, and manage it without a UC team. The work that used to take PowerShell and spreadsheets is software now.

Why move

You're already paying for the new way.

Most organizations run a phone system their Microsoft licensing already covers — a legacy PBX on one budget line, under-utilized 365 on another. Side by side, it isn't close: in cost, in effort, or in what your helpdesk can handle alone.

The old way

Paying twice for phones in a 365 world.

Legacy PBX and carrier costs consume the budget — while the Microsoft licensing they already own sits under-utilized
Basic support issues need senior IT — PowerShell, carrier portals, spreadsheets
Every change is a project; every project waits on a specialist
The new way

Just Voice in Teams.

One unified experience, powered by Microsoft 365 — phone licensing bundled in E5, additive to E1, E3, and frontline SKUs
User setup, licenses, and dial plans configured automatically
Coming soon: Voice data feeding Copilot — every call making the AI smarter
Migration

Know exactly what you have, before you touch anything.

Most migrations go wrong because no one fully knows the system they're replacing. We start by documenting it — automatically, and accurately.

Automated assessments
Discover your phone system without manual audits. We map configurations, devices, and dependencies for you.
Automated & accurate
Usage verification
See who actually calls, how often, and from where — so you migrate what's used and retire what isn't.
Real usage data
PBX documentation
A complete, written record of your legacy PBX— the documentation no one ever had time to make.
Single source of truth
Requirements development
Turn assessment data into a clear migration plan: time, effort, roles, and responsibilities, all scoped.
Plan with eyes open
Savings model
See what moving off your on-premises PBX is worth — clients save up to 70% against legacy systems.
Up to 70% saved
Calling-plan fit
Compare Microsoft Calling Plans, Operator Connect, and Direct Routing, and land on the right path.
The right route
Automation

Move in days, not months.

Assessment data feeds straight into porting and provisioning. We carry the carriers, the numbers, and the call flows — so cutover stays quiet.

The difference

No PowerShell. No templates. No Excel-Hell.

Configure Teams voice — Direct Routing, voicemail, dial plans, and policies — without scripts, without the admin center, and without a specialist. If your helpdesk can use a web app, they can run your phone system.

“ZIRO didn’t just sell us a solution—they became an extension of our team. Their patience and responsiveness turned a chaotic transition into a manageable process.”

Greg Bartholomew — IT Director

Every approach solves part of it. ZIRO solves the whole lifecycle.

Provisioning platforms run day-two but can't migrate you. Migration specialists move you, then disappear. ZIRO is the one platform built for the full journey.
